Saving the Delta requires sacrifice by all, not just residents of this region. I hope someone drilled that idea into the State Water Resources Control Board. The board, whose Sisyphean job is to ensure California’s water is used fairly, brought its road show to Stockton last Friday for a public hearing on its dubious Water Quality Control Plan.To save dying fisheries, and to make the Delta healthier, the board proposes to bump up flows on three rivers that feed the San Joaquin River: the Stanislaus, Tuolumne and Merced.
